Intercom & Telephone Entry Systems We Install & Support

Analog Intercom Systems
Analog intercom systems are a dependable solution for buildings that require straightforward voice communication and controlled entry without relying on internet connectivity.
These systems are commonly used in older buildings, smaller commercial properties, and locations where simplicity and reliability are the priority. Analog intercoms are known for their durability and consistent performance in high-use environments.
Best suited for:
- Existing buildings with legacy wiring
- Properties seeking a cost-effective upgrade
- Environments where internet connectivity is limited or unnecessary

Wi-Fi Intercom Systems
Wi-Fi intercom systems offer modern access control with advanced features such as video verification, mobile device connectivity, and remote access management.
These systems allow authorized users to answer calls, view visitors, and unlock doors from smartphones or tablets, making them ideal for properties that require flexibility and real-time access control.
Best suited for:
- Apartment buildings and multi-tenant properties
- Commercial offices with remote management needs
- Properties upgrading from outdated intercom systems

Telephone Intercom Systems
Telephone-based intercom systems route calls directly to landlines or mobile phones, allowing tenants or staff to communicate with visitors and grant access without being physically on site.
These systems are widely used in managed properties where convenience, familiarity, and ease of use are important for daily operations.
Best suited for:
- Multi-tenant residential buildings
- Commercial properties with off-site management
- Buildings seeking a simple, user-friendly solution

Choosing the Right Intercom System for Your Building
Each intercom type serves a different purpose, and the right choice depends on your building layout, number of users, access points, and management preferences. Our team evaluates these factors during an on-site assessment to recommend a system that delivers security, usability, and long-term value.
Intercoms Integrated With Your Building’s Security Systems
Intercom systems are most effective when they function as part of a complete security ecosystem.
Our installations are commonly integrated with:
- Access control systems
- Electric strikes and magnetic locks
- Fire-rated and security door hardware
- CCTV and security camera systems
This integrated approach allows property managers to control entry points, monitor activity, and maintain compliance without juggling disconnected systems.
